IMPROVEMENT 1N KINDLING-.wooa

Specification forming part of Letters Patent N o. 107,319, dated September 13,1870.

To all Loh/0m it-ty concern: A

Be it knownthat I, MERRITT T. ARNOLD,

of Summit, in the county Of Kent and Statevof vRhode Island, have invented a new and-j valuable Improvement in Means for Manufac-v turing Kindling-Wood and Pyroligneous Acid by one Process; and I do hereby declare that vthe following is a full, clear, and exact de scription Of the construction and Operation of the same, reference being had to the annexed drawings, making a part of this specification, aud to the letters and figures Of reference marked thereon.

Figure 1 of the drawings is a representation A of the drawingsl represents abox or chest, I with twO or more apertures in its front end,

adapted'to receive'the, strong iron cylinders B. These openings are cylindrical in form; and are made immediately above the interior plate above the iirespaces, and so arranged that when the cylinders are inserted they rest, respectively, upon said interior platev This interior plate is marked c on the drawings, The cylinders B are closed at their rea-r ends, but their front is open, fOr-the purpose Of receivingthe kindlingwood, as hereinafter mentioned. The method of closing the front ends ofthese cylinders is represented on Fig. 1; and it consists Of the construction of the removable heads D, which are vadapted for attachment to the cylinders by screws, which pass through their rims and into the openings marked d.

My fire-places are represented by the let! process whereby both' ters H. *At-,the rear ends 'of eacli` cylinder,

and at the extreme lower side thereof, I makea small aperture, and connect therewith v`a pipe, markedl K, which pipe'is passed through a tank of cold water, and from thence to a-prOper receptacle of pyroligneous acid. To operate my device I rst saw and spllt wood'into very small fragments,vof a size suitable for kindling-wood, andll therewith the' cylinders I then attach the heads of vsaid cylinders, Vas described, and pack the jointsclosely with lute. `I then build a reunder the cylinders and heat theminte'nsely. The pyroligneous acid of the kindling-wood is-car, ried Off in the form of vapor` in the' tube K, and is condensed in the cold-water tank ro. ferred'to;'

4Inasmuch as -a leading Object of my device is to prepare kindling-wood for use and not to destroy it, I slackenthe -iires and 4'cease the heat upon such wood when itis about reachf ing the point of being changed into cha1c )a l;

or, in other language, whileI heat ously I do notallow it to char. v When the process above described is intelliit vigorgently and carefully followed, t-he result `willl be from twenty to eighty per cent. of the pyroligneous'acid of the timber will be secured, and at the same time the kindling-Wood will be thoroughlydried andmade readvfor use.

1. The furnace herein described, havingfbox A, lcylinders B, withxremov'able heads D, iireplaces H, central plate,lc, and condensingfpip'e 'K, when lconstructed and arranged ltooperate .as specified. v

2. The kindlingfwoo'd herein described, when prepared `by the ,process'specied as a new article of manufacture.

In testimony that I claim the aboveI have hereunto subscribed myname inthe presence MERRLTT T. ARNOLD Of two witnesses.
